I Know What You Did Last Summer Movie Storyline

The sleepy coastal town of Summersend is shattered when Danica Richards, Ava Brucks, Milo Griffin, and Teddy Spencer, bound by years of friendship, make a fatal mistake on graduation night. Driving back from a secluded beach party, their reckless joyride ends in tragedy when they accidentally hit and seemingly kill a local fisherman. Panicked and fueled by youthful fear, they make a pact to bury the body and never speak of the incident again, hoping to leave their past behind. One year later, the friends find their lives spiraling into a nightmare as each receives a cryptic, threatening message: “I know what you did last summer.” As the anniversary of the accident approaches, a relentless and unseen stalker begins to systematically torment them, recreating the gruesome details of that night and escalating to violent attacks. Danica, plagued by guilt, struggles to maintain her composure and becomes determined to uncover the identity of their tormentor before they all become victims. Meanwhile, Ava’s carefree facade crumbles under the weight of paranoia, and Milo, the group’s self-proclaimed leader, attempts to take control of the situation, only to find himself increasingly isolated. Teddy, impulsive and reckless, acts out, drawing unwanted attention and further endangering them all. As they desperately search for answers, long-buried secrets within their tight-knit community begin to surface, revealing a web of hidden resentments and potential suspects. The friends soon realize that their shared secret has made them targets, and that the killer is not only seeking revenge for the fisherman’s death but also intends to punish them for their moral failings, leading to a bloody confrontation where the true identity of the vengeful stalker is revealed, forever changing the landscape of their lives.
